CORN-PLANTER.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed January 4, 1907. Serial No. 350,729.

Ohio, have invented certain new and useful I Improvements inCorn-Planters; and I do tion.

hereby declare that the following is a full, clear, and exactdescription of the sane, reference being had to the annexed drawing,making a part of this specification, and to the numerals and figures ofreference marked thereon, in which the figure of the drawing is a topplan view showing the different parts properly arranged with referenceto each other.

The present invention has relation to cornplanters designed to plantthree rows of grain at a time; and it consists in the novel arrangementhereinafter described, and particularly pointed out in the claims.

In the accompanying drawing, which is a plan view of the machine, 1represents the axlebearings, which bearings are secured in anyconvenient and wellknown manner to the frame of the planter proper, inwhich bearings is journaled the main axle 2, upon which axle is mountedthe bearing and covering wheels 3, Which parts within themselves fOIiIlno particular part of the present invention. The parallel bars 4 extenda short distance forward of the axle and extend rearward and are for thepurpose of holding in proper spaced relation the axle 5 and shaft 6. Thebars 4: may be continuous, or they may be made in separate pieces andconnected together.

For the purpose of providing means for attaching the various parts ofthe planter the side frames 7 are provided, which side frames aresubstantially of the form shown and may be connected in any convenientand well-known manner; but the part constituting, the frame withinitself does not enter into the present invention to any extent, andhence no detailed description is necessary.

For the purpose of elevating and adjusting the frame the foot-lever 8 isprovided, which foot-lever is properly connected and is operated in heusual manner. Upon the shaft 5 is mounted the combined covering, marker,and dropmechanismoperating wheel 9, which is located directly in therear of the center or middle row dropping-box 10, and upon either sideof the middle dropping-box 10 are located the dropping-boxes 11, whichdropping-boxes are provided with the usual ,mechanism for dropping thegrain, (not illustrated) so that it will find its way through ordinarydropp ng-spouts, which are located in rear of the runners orfurrowopeners 12, whlch are of the usual construc- For the purpose ofsupporting the dropping-boxes 10 and 11, together with the differentparts connected and belonging thereto, the frame 13 is provided, whichfraine is attached to the main frame in any convenient and well-knownmanner. The combined covering, marker, and graindropper-mechanismoperating wheel 9 is preferably formed of tWo tires 14,spaced apart and held in proper spaced relationship with reference toeach other by the connecting-yokes 15, which yokes are connected to theoody or hub of the wheel proper. Upon the tires 14 are located themarker-blocks 16, which marker-blocks serve the double purpose ofmarking and preventing any slipping of the wheels, by which arrangementa positive motion is imparted to the shaft 17, which shaft is for thepurpose of communi eating motion to the dropper mechanism as theplanter-fra ne is moved over the ground in the usual manner.

It will be understood that by providing the marker-blocks they willserve the purpose of the common check lines or Wires and the grain canbe planted in straight rows in opposite directions.

Upon the axle 5 is mounted the sprocket- Wheel 18, from which leads thesprocketchain 19 to and around the sprocket-wheel 20, whichsprocket-wheel is mounted on the shaft 6. Upon the shaft 6 is mountedthe sprocket-wheel 21, from which sprocketwheel leads the chain 22 toand around the sprocket-wheel 23, which sprocket-wheel is mounted uponthe shaft 24. The chain 22 is provided with the laterally-extending lugs25, which are for the purpose of engaging the arms 26, which arms arefixed to the wheel 27, which wheel is securely mounted upon the shaft17. It will be understood that when motion is imparted to the chain 22intermittent rotary motion will be imparted to the shaft 17, therebyimparting an intermittent motion to the dropping mechanism, located inthe usual manner in the dropperboxes 10 and 11, and of course theordinary mechanism is employed for operativcly conneeting thedropper-plates to the intermittent shaft 17.

For the purpose of holding the upper member of the drive-chain 22 inproper relationship with the arms 26 the roller-idler 28 is provided,which roller is journaled directly above the chain 22. In the drawing Ihave illustrated wheel-scraper blades 29, which are connected andoperated in the usual manner.

The marker-blocks 16 serve the double purpose of marking at right anglesto the travel of the frame and to actuate the graindropping mechanismthrough the mechanism located intermediate the operating-wheel and thegrain-dropping mechanism.

Il aving fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a three-row planter, a frame mounted upon bearing-wheels, saidframe carrying seedboxes, a marker-wheel journaled in a frame at therear of the center or middle seed box, the axle of said marker-wheelcarrying a sprocket-wheel, a sprocket-chain engaging a sprocket-wheel ona shaft midway of the frame, a second sprocket-wheel on said shaft, asprocketchain engaging a sprocketwheel on a forward shaft for operatingthe seed-feeding devices, substantially as and for the purposesspecified.

In a corn-planter, a frame mounted upon bearing-wheels, said framecarrying seedboxes, a marker-wheel ournaled in a frame at the rear ofthe center or middle seedbox, the axle of said marker-wheel carrying asprocket-wheel, a sprocket-chain engaging a sprocket-wheel on a shaftmidway of the frame, a second sprocket-wheel on said shaft, asprocket-chain engaging a sprocket-wheel on a forward shaft foroperating the seeding a sprocket-wheel, a sprocket-chain engaging asprocket-wheel on a shaft mid way of the frame, a second sprocket-wheelon said shaft, a sprocket-chain engaging a sprocketwheel on a forwardshaft, said chain provided with lugs, a seed-dropping shaft providedwith arms, and the lugs on the chain adapted for actuating the arms uponthe seed-dropping shaft, substantially as and for the purposesspecified.

4. In a corn-planter, a frame mounted upon bearing-wheels, said framecarrying seedboxes, a marker-Wheel mounted upon an axle, said axlejournaled in a frame at the rear of the seedboxes,a sprocket-Wheelmounted upon the marker-Wheel axle, a sprocket-chain engaging asprocket-wheel on a shaft midway of the frame, a second sprocket-wheelon said shaft, a sprocketchain engaging a sprocket-wheel on a forwardshaft, said chain provided with lateral lugs, a seed-dropping shaftprovided with arms, and the lateral lugs upon the sprocket-chain adaptedfor engagement with the arms upon the seed-dropping shaft, substantiallyas and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
